Testosterone test: Adding testosterone to Viagra does not lead to better erections or otherwise improve sexual functioning in men with low testosterone, a new study shows. Viagra alone worked just as well as Viagra plus testosterone gel for the men in the study. Testosterone may have other benefits for such men, though, and individual results may vary, doctors say.
